ABSTRACT
The technological changes occurring in an economic situation appear first in the nature of manufactured products and in the way they are produced. From the given 1962 technological situation, where basic products prevailed, economic production massively changed towards a rapid growth of non-primary products: production of industrial goods of different categories, and also of modem services, both still little known in the Algerian society in such high quantities and in such variety. Each growth point represents an absolute production volume which increases with the gross domestic product (GDP). High rates of growth can be observed in the economy during this entire period with the exception of a slight recession between 1973 and 1977. Since there are no documents to show the evolution of the GDP between 1979 and 1984 at constant prices, readers have made an estimate based on a nine per cent per year price rise hypothesis for the whole period.
